Code Inspector 3D turns building code learning into something you can actually see. Instead of paging through a code book, you explore richly illustrated cutaway views of a house โ€” one for every major building discipline โ€” and tap directly on real components to learn what they are, what inspectors check, and which code sections govern them. WHAT YOU CAN EXPLORE 13 illustrated disciplines, each with its own detailed cutaway view and dozens of tappable inspection points: Electrical โ€” service entrance through branch circuits, grounding, GFCI/AFCI protection Mechanical & HVAC โ€” furnaces, air handlers, ductwork, refrigerant piping, ventilation Plumbing โ€” water supply, DWV, fixtures, backflow prevention, venting Architectural โ€” egress, fire separation, stairs, guards, accessibility Structural โ€” load path from roof to foundation, connections, bracing Civil โ€” site drainage, grading, footings, utility connections Fire Alarm โ€” detection, notification, control panels, standby power Security & Low-Voltage โ€” cameras, access control, structured cabling Communications & Data โ€” structured cabling, network infrastructure Building Automation โ€” sensors, controllers, actuators Solar & EV Charging โ€” PV interconnection, battery storage, EVSE circuits TAP TO LEARN Every marker opens a detailed panel covering purpose and key requirements, inspection points a real inspector checks, measurements and clearances with code citations, common violations explained in plain language, code references tagged by type (Code Requirement, Local Amendment, Recommended Practice, Educational, or Manufacturer Requirement), and cross-discipline relationships. SCHEMATICS Every discipline also includes a 2D riser or single-line diagram, so you can see how components connect beyond what one illustration angle can show. FOUR WAYS TO USE IT Explore Mode โ€” tap and learn at your own pace Learning Mode โ€” a relaxed, no-pressure study mode Inspection Mode โ€” work through structured checklists by discipline, mark Pass/Fail/Needs Review, and compile a report Violation Training Mode โ€” the app seeds intentional code violations across the model; find them, report them, and get instant feedback with the fix explained LEARNING HUB (FREE) Study without buying anything: an app guide, glossary, guided tour, quiz, and a Building Disciplines reference covering all 30 conceptual disciplines in the building industry. GALLERY A 70-image reference gallery of NEC and fire alarm inspection illustrations, viewable full-screen with pinch-to-zoom. WHO IT'S FOR Built for inspectors-in-training, contractors, electricians, HVAC and plumbing technicians, architecture and construction students, and homeowners who want to understand what's really behind their walls. Code Inspector 3D references NEC (NFPA 70), IRC, IMC, IPC, IBC, and NFPA 72 as its baseline. Always verify against your local Authority Having Jurisdiction โ€” this app is an educational tool, not a substitute for your local code official. The Learning Hub is free to explore. Everything else โ€” every illustrated discipline, schematics, code search, the illustration gallery, and inspection tools โ€” unlocks with a single one-time purchase. No subscription, no ads.

ICC B1, B2 & F3 Exam Prep

Kalyta is an AI-native study companion for three ICC certification exams: B1 Residential Building Inspector, B2 Commercial Building Inspector and F3 Fire Plans Examiner. It adapts to what you keep missing, explains every answer, and because these exams are open book, it shows where each provision lives in your own edition of the code. THE EXAMS All three are ICC National Certification exams: multiple choice with four options each, no calculator, sat open book, and offered against both the 2021 and the 2024 code editions. - B1 Residential Building Inspector: 60 questions in 120 minutes, against the International Residential Code (IRC). - B2 Commercial Building Inspector: 80 questions in 210 minutes, against the International Building Code (IBC). - F3 Fire Plans Examiner: 60 questions in 210 minutes, against the International Fire Code (IFC), with the parts of the IBC its outline covers. BUILT FOR AN OPEN-BOOK EXAM Open book means these exams are not really memory tests. They are search tests, under the clock. After you answer, Kalyta shows where that rule sits in your edition of the code: the chapter and its title, every parent heading above it, and the part of the section the provision is in, and on the F3, which book it is in. You practice the lookup, not just the answer. CHOOSE YOUR CODE EDITION You sit the exam against one edition, and a rule often stays put while its section number moves. Pick 2021 or 2024, and the questions, lessons and lookups are all served for that book. EVERY CONTENT AREA Every content area of ICC's published outline for each exam is covered, in both code editions: practice questions with worked explanations, concept lessons, and a section lookup on every question. WHAT YOU GET - Adaptive practice: questions are chosen around your current level and mixed with spaced review, so your time goes where it moves your result. - A worked explanation on every question: why the right answer is right, and why each of the others is wrong. - A section lookup after every answer, pointing into the edition you chose. - Concept lessons: short, focused reading on the rule behind the question. - An AI tutor you can steer: ask why an answer works, ask for another example, or tell it to slow down. - Timed rehearsals in each exam's format, drawn across its content areas and reported as the number you answered correctly. - Review and progress: revisit a rehearsal question by question, watch your accuracy trend, and see which content areas are weak. HONEST BY DESIGN ICC reports these exams as a scale score, not a percentage, so Kalyta does not predict your result or your chance of passing. We publish no pass rates, score improvements or testimonials. Kalyta is study material, so it stays outside the exam room: ICC permits bound code books and approved references, not study guides or practice questions. Kalyta is an independent study tool, not endorsed by or affiliated with the International Code Council. ICC, International Residential Code, IRC, International Building Code, IBC, International Fire Code and IFC are trademarks of the International Code Council, Inc. Kalyta does not reproduce the code and is not a substitute for the books you bring to the exam. HOW THE FREE ACCESS WORKS Your first seven study days are free.
